WHY LIFT-ALL WEB SLINGS?
Lift-All web slings meet or exceed OSHA, ASME B30.9 and WSTDA standards and regulations.
All of the sling webbing contained in this catalog is
recommended for general purpose lifting. Military webbing, sometimes designated as "Mil-Spec", has not been
designed for, nor do we recommend it for general lifting
applications.
Refer to Lift-All Sling Webbing Diagram
• Sling webbing, as shown, has its surface yarns connected from side to side, which not only protect the core
yarns, but positions all surface and tensile yarns to
work together to support the load.
What is the Difference?
• Wear or damage to Sling Webbing face yarns cause
Refer to Mil-Spec Webbing Diagram
an immediate strength loss. This is why Sling Webbing has red core yarns to visually reveal damage and
act as a basis for sling rejection.
• Mil-Spec webbing does not have red core yarn warning system.
• Mil-Spec webbing supports the entire load with exposed surface yarns. Lift-All sling webbing uses a
combination of internal protected yarns and surface
yarns.
• Damage to the surface of Mil-Spec webbing causes
greater strength reduction of the webbing.

INSPECTION CRITERIA FOR WEB SLINGS
All slings should be inspected for damage prior to each use
to assure that their strength has not been compromised. The
following photos illustrate some of the common damage that
occurs to indicate that the sling should be taken out of service.
THE DAMAGE: Surface and Edge Cuts - It is important to
realize that all of the fibers in web slings contribute to the
strength of that sling. When there have been a significant
number of fibers broken in a web sling, as shown here, that
sling should be taken out of service.
WHAT TO LOOK FOR: Broken fibers of equal length indicate that the sling has been cut by an edge. Red core
warning yarns may or may not be visible with cuts and
are not required to show before removing slings from
service.
TO PREVENT: Use wear pads (see page 123) between
the sling and all edges that come in contact with the sling.
THE DAMAGE: Holes/Snags/Pulls
WHAT TO LOOK FOR: Punctures or areas
where fibers stand out from the rest of the sling
surface.
TO PREVENT: Avoid sling contact with
protrusions, both during lifts and while
transporting or storing.
16
THE DAMAGE: Abrasion
WHAT TO LOOK FOR: Areas of the sling that look
and feel fuzzy indicate that the fibers have been broken by being subject to contact and movement
against a rough surface. Affected areas are usually
stained.
TO PREVENT: Never drag slings along the ground.
Never pull slings from under loads that are resting
on the sling. Use wear pads between slings and rough
surface loads.
Web Slings
Web Slings
INSPECTION CRITERIA FOR WEB SLINGS
THE DAMAGE: Heat/Chemical
WHAT TO LOOK FOR: Melted or charred fibers
anywhere along the sling. Heat and chemical
damage can look similar and they both have the
effect of damaging sling fibers and compromising
the sling's strength. Look for discoloration and/or
fibers that have been fused together and often
feel hard or crunchy.
TO PREVENT: Never use nylon or polyester slings
where they can be exposed to temperatures in
excess of 200° F. Never use nylon or polyester
slings in or around chemicals without confirming
that the sling material is compatible with the
chemicals being used.
THE DAMAGE: Knots compromise the strength of
all slings by not allowing all fibers to contribute to the
lift as designed. Knots may reduce sling strength by
up to 50%.
WHAT TO LOOK FOR: Knots are rather obvious
problems as shown below.
TO PREVENT: Never tie knots in slings and never
use slings that are knotted.
THE DAMAGE: Broken/Worn Stitching in the main
stitch patterns of web slings has a direct adverse effect
on the strength of a sling. The stitch patterns in web slings
have been engineered to produce the most strength out
of the webbing. If the stitching is not fully intact, the
strength of the sling may be affected.
WHAT TO LOOK FOR: Loose or broken threads in
the main stitch patterns.
TO PREVENT: Never pull slings from beneath loads
where stitch patterns can get hung up or snagged. Never
overload the slings or allow the load edge to directly contact the stitch pattern while lifting. Never place a sling
eye over a hook or other attachment whose width/diameter exceeds 1/3 the eye length.
THE DAMAGE: Illegible or Missing Tags- The information provided by the sling tag is important for knowing what sling to use and how it will function.
WHAT TO LOOK FOR: If you cannot find or read all of
the information on a sling tag, OSHA requires that the
sling shall be taken out of service.
TO PREVENT: Never set loads down on top of slings or
pull sling from beneath loads if there is any resistance.
Load edges should never contact sling tags during the
lift. Avoid paint or chemical contact with tags.
Red Core Yarns - are an additional warning of dangerous sling damage. All standard Lift-All Web Slings have
this warning feature. When red yarns are visible, the sling
should be removed from service immediately. The red core
yarns become exposed when the sling surface is cut or
worn through the woven face yarns. For other inspection
criteria see OSHA/Manufacturer regulations on pages 6
through 8.

STANDARD WEB SLING TYPES
Hardware Slings
Unilink and Web-Trap hardware can help to extend sling
life by protecting the webbing from abrasion on rough
crane hooks. Hardware can often be reused, lowering
sling replacement costs.
Type U (UU) - Has the preferred and economical Unilink
fitting on each end for use in a vertical, choker or basket
hitch. Unilinks allow choking from either end to save
time and vary wear points. See page 22.
Type 1 (TC) - Has a Web-Trap triangle and choker fitting
on either end. Typical use is in a choker hitch. Can also
be used in vertical and basket hitches.
Type U
Type 1
Type 2 (TT) - Has a Web-Trap triangle on each end.
Normally used in a basket hitch, but can also be used in
a vertical hitch. They cannot be used as a choker.
Type 2
Eye Type
Type 3 (EE) - Flat Eye slings are very popular and can
be used in all three types of hitches. They are easier to
remove from beneath the load than sling types 1, 2 and
4. Unless type 4 is requested, type 3 will be supplied as
the standard EE sling.
Type 4 (EE) - Twisted Eye slings are similar to Type 3
except the eyes are turned 90° to form a better choker
hitch. The eyes of a Type 4 nest better on the crane
hook.
Type 3
Type 4
Endless Type
Type 5 (EN) - Endless slings are versatile and the most
economically priced. They can be used in all three types
of hitches. The sling can be rotated to minimize wear.
The sling legs can be spread for improved load balance.
Reverse Eye Type
Type 6 (RE)-An endless sling with butted edges sewn
together to double the sling width. They have reinforced
eyes and wear pads on both sides of body and eyes.
The result is an extremely strong and durable sling.

WEB SLING EYE TREATMENTS
Eye Wear Pads - The eyes of web slings are often subjected to the harsh treatment of rough crane hooks.
Specialty eye treatments are available to help reduce the wear in that area, thereby extending sling life.
The following photos illustrate the more common eye treatments using wear resistant webbing in
various forms. Should you want non-standard eye treatment on your eye & eye web slings, please
specify using the terminology below.

Other wear pad materials are available (see page 123).
Tapering Eyes - As a standard practice, the eyes, or bearing points of sling Types 3 and 4 are tapered to
accommodate a crane hook on slings that are 3" and wider. Untapered eyes are available upon request. Type 5
(Endless) slings are NOT tapered unless specified on order. Dura-Web 2000 slings are not tapered in any width.

Tuff-Tag and Warning Sheet
Anti-Abrasion Treatment
Lift-All recommends that web slings be manufactured
from abrasion resistant latex treated webbing.
Treatment is standard on both nylon and polyester web
slings. Natural, untreated webbing is available upon
request.
Note: Heavy duty treatments are available as a
supplemental process for greater protection.
Elasticity - The stretch characteristics of web slings
depends on the type of yarn and the web finish.
Approximate stretch at RATED SLING CAPACITY is:
NYLON
OSHA requires all web slings to show rated capacities and type of material. The Lift-All Tuff-Tag is
made from an abrasion resistant polymer that will
remain legible far longer than any leather or vinyl
tags. In fact, a Tuff-Tag will consistently outlast the
useful life of a sling.
A Warning Sheet is included with every web sling
order from Lift-All. The
sheet lists inspection information and operating practices applying to synthetic
web slings.
